Crest audio PL3301 SPECIFICATIONS

Product Description
The Crest Audio PL3301 professional power amplifier is designed to achieve unsurpassed sonic performance and long­term reliability—even when operating under extreme stress—in touring or fixed installation applications.
Absolute sonic accuracy is the hallmark of every Crest amplifier. Bass is solid and defined to the limits of audibility, with ample current reserves delivered by an “over-engineered” power supply and advanced Class AB output circuit design. Wide-bandwidth output devices assure detailed, transparent high frequency response.
Construction and Quality Control
The PL3301 is built exclusively in Crest’s own USA manufactur­ing facility, with internal components selected for premium qual­ity and proven durability. Each modular subassembly is pre-test­ed, and the assembled PL3301 receives a rigorous “hot room” burn-in before thorough final checkout on precision test equip­ment.

protection circuits:
- ACL (Active Clip Limiting) prevents speaker damage with gentle gain reduction at clip threshold.
- IGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may overstress output devices.
- AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on.
- TourClass also includes comprehensive thermal manage­ment, and short circuit, DC voltage, turn-on/off transient, current inrush and sub/ultrasonic input protection.
• Input sensitivity selection
• Recessed, stepped attenuators
• Front panel circuit breaker switch
• Modular construction
• Three-year warranty

Architect’s & Engineer’s Specifications
The power amplifier shall have two channels. At 8 ohms, 20Hz
- 20kHz, 0.1% THD, it shall deliver a minimum of 150 watts per channel. At 4 ohms, 20Hz - 20kHz, 0.1% THD, it shall deliver a minimum of 200 watts per channel. In bridged mono mode with an 8 ohm load, 20Hz - 20kHz, 0.1% THD, it shall deliver a minimum of 450 watts. The amplifier shall have circuitry to protect itself from output short circuits, thermal overload or other adverse load condi­tions. The amplifier shall protect speaker loads from DC volt­age on outputs. The amplifier shall have active clip limiting and impedance sensing circuitry. Output relays shall protect the speakers from amplifier failure. Two rear panel mounted variable speed DC fans (filters detachable without tools) shall provide back to front air flow through the chassis. Each channel shall have a standard (factory-set) input sensitiv­ity of 0.775 Volts, and shall be fitted with an internal jumper which allows the gain to be altered to X20 or X40. The hum and noise level shall be 105 dB below rated output, “A” weighted. SMPTE IMD shall be less than 0.01% at rated power, 60Hz and 7kHz. The amplifier shall have a class AB output stage. The frequency response shall be 20Hz-20kHz, +0, -0.3dB (1W/8). The amplifier will operate at 100V-240V, 50-60 Hz AC (config­ured at factory). Maximum current draw shall not exceed 9 amperes at 120VAC (limited by front panel breaker for bench tests). Front panel indicators shall include Active, Protect, Signal, and Clip LED’s for each channel. Front panel attenuators shall be recessed and detented. Rear panel input connectors shall be female TRS and XLR type, internally dealer-configurable for pin 2 (factory setting) or pin 3 positive. Output terminations shall be 5-way output binding posts. A ground lift switch and a Stereo/ Parallel/Bridged Mono mode operation switch shall be provid­ed. A rear-panel IEC AC mains socket (with power cord) or single AC mains cord having an appropriate AC plug for the intended operating voltage shall be provided (market dependent). The packaging of the amplifier shall allow for standard rack mounting without requiring space between similar units. Optional rack mount handles will be available. Dimensions shall be 19" (483mm) wide, 3.5" (89mm) high and 17.85" (454mm) deep. The amplifier shall weigh 33 lbs. (14.98 kg) net, and shall be designated the Crest Audio model PL3301.
